Hot Zone Trigger Method for Location-Based Services
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional positioning systems in battery-operated devices consume excessive power, limiting their ability to continuously track locations and deliver location-based services without user input, as they are typically only enabled on demand due to power constraints.
Innovation Solution
A method for generating position signals and trigger signals that indicate crossing, entering, or leaving 'hot zones' to minimize power consumption by adapting application modules between low and high power modes, allowing continuous location tracking and service delivery with reduced energy use.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If the positioning system continuously tracks the location of the device, then location-based services can be proactively delivered to the user, but the power consumption of the positioning system and applications increases
Solution Approach 1:
The system uses periodic position updates triggered by zone boundary crossings instead of continuous monitoring. The positioning system is activated only when needed to detect entry into or exit from predefined geographic zones, thereby reducing overall power consumption while maintaining the ability to deliver location-based services proactively
Solution Approach 2:
The system automatically activates the positioning system and relevant applications when a zone boundary is crossed, and automatically deactivates them when leaving the zone. This self-service mechanism eliminates the need for continuous user input or manual system management, optimizing power usage based on actual service needs
2Use of energy by moving object
If the positioning system is enabled on demand from the user, then power consumption is reduced, but location-based services can only be delivered following an explicit user request
Solution Approach 1:
The system pre-defines geographic zones and associates applications with these zones in advance. When the device enters a predefined zone, the corresponding application is automatically activated without requiring user initiation. This preliminary setup enables proactive service delivery while maintaining low power consumption by only activating systems when geographically triggered
3Reliability
If applications remain active to provide continuous location-based services, then service availability is improved, but power consumption increases
Solution Approach 1:
The system activates applications locally and selectively based on the geographic zone entered, rather than keeping all applications continuously active. Each application is associated with specific geographic zones and is only executed when the device enters those zones, ensuring service availability when needed while minimizing overall power consumption

AI summary
A method for location-based zone triggering is disclosed. The method generally includes the step of (A) generating a position signal conveying a location of a device in at least two spatial dimensions in response to a plurality of navigation signals received from external the device and (B) generating a trigger signal at an interface based on the position signal, (i) a first aspect of the trigger signal indicating that the location is crossing a boundary of a zone, (ii) a second aspect of the trigger signal indicating that the device is one of entering the zone and leaving the zone and (iii) the interface adapting a zone module to communicate the trigger signal to an application module.
